TECHNICAL SPECIFICATION OF AGRO RESIDUE BASED BIO-MASS

PALLETS (NON- TORREFIED/ TORREFIED) FOR CO- FIRING IN COAL

BASED THERMAL POWER PLANTS

1.0 GENERAL

The burning of agro residue/ stubble in- situ by farmers after crop is harvested has been

one of the reason for environmental pollution having adverse health impacts.

Co- firing of biomass alongwith coal in coal based thermal power plants to produce

electricity is an efficient way of utilizing the agro residue and avoiding the

environmental pollution, at the same time generating extra revenue to the farmers by

sale of agro residue as raw material input to the pellets manufacturer. However, the raw

agro residue cannot be directly utilized in thermal power plants as coal mill are not

designed to pulverize the fibrous biomass and same needs to be densified and processed

to form the pellets having pre- pulverised fine constituent particles. The densified

biomass pellets/ torrefied pellets can be fed to the mills and easily crushed with coal for

firing into the boiler.

Considering merits of using the agro residue based biomass pellets for power generation

through co- firing alongwith coal in thermal power plants, Ministry of Power has

brought out the policy for “Biomass utilization for power generation through co-firing

in coal based power plants”. The policy has been uploaded on the CEA website. As per the policy all fluidised bed and pulverised coal units (coal based thermal power plants)

except those having ball and tube mill, of power generation utilities, public or private,

located in India, shall endeavour to use 5-10% blend of biomass pellets made, primarily,

of agro residue along with coal after assessing the technical feasibility, viz. safety

aspects etc.

In line with the policy, CEA has also issued an advisory to all the Thermal Power

Generating Plants/Utilities to endeavor to use 5-10% blend of biomass pellets made,

primarily, of agro residue along with coal after assessing the technical feasibility, viz.

safety aspects etc. Further, as per policy, CEA is required to develop/issue the

specification for the biomass pellets and provide technical assistance/advice to utilities

on how to use bio-mass pellets for blending with coal in coal based thermal power plants.

2.0 INTENT OF SPECIFICATION

The intent of this specification is to cover the various relevant aspects and requirements

of agro residue based biomass pellets (non- torrefied/ torrefied) to be supplied to a coal

based thermal power plant for co- firing in the boilers alongwith coal.

The utilities are required to review the technical parameters indicated in this

specification and make suitable modifications, if required, considering the broad

characteristics of biomass pellets likely to be available for supply to their power plant.

3.0 SCOPE OF WORK

The scope of work of the bidder shall include manufacture, supply, loading, transport and delivery of non- torrefied/ torrefied biomass pellets at ……. x…….MW coal based thermal power plant of M/s …………….. (Owner) located at ……………. . The bidder shall supply the pellets in loose form filled in the carriage vehicles (closed/ covered containers) and these shall be unloaded in the power plant at the area identified by the owner for this purpose. The biomass pellets supplied shall primarily be made of agro residue and these shall adhere to the technical requirements indicated in this specification.

4.0 QUANTITY TO BE SUPPLIED & DELIVERY SCHEDULE

The quantity of biomass pellets to be supplied by the bidder shall be ……. metric tonnes per day (tpd) on regular basis for a period of …..… days/ months/ years. However, depending upon quantity to be supplied, the bidder can also supply the consignment of pellets at frequency of one consignment per more than one day, as per mutual agreement with the owner. The supply of biomass pellets to the power plant shall begin from date …..… . The total quantity of biomass pellets to be supplied by the bidder during the contract period shall be about …..… metric tonnes. The consignment of biomass pellets shall be delivered at owner’s thermal power plant, transported by trucks/dumpers. If required by owner, as per reasons attributable to the power plant, the scheduled quantity of pellets to be supplied by the bidder to the power plant may change. In such case, the changed delivery schedule shall be sent by owner to the supplier, say three (3) day in advance at his official e-mail ID or by other means, indicating revised quantity of biomass pellets to be delivered (which may even be zero) and supplier shall dispatch the consignment accordingly.

5.0 RAW MATERIALS & PELLETISATION PROCESSES 5.1 Raw Materials

For manufacturing of non- torrefied/ torrefied biomass pellets, the raw materials to be used shall primarily be the surplus agro residue/ crop residue which remain unutilized after harvesting the crop and is otherwise being burnt by the farmers in the field. The type and availability of such surplus agro residue shall vary from region to region as per crop pattern and extent of farm residue being utilized for various purposes. For example, for north western region of the country, the agro residue/ farm residue likely to be available as surplus for making of pellets are paddy stubbles/ straw & husk, cotton stalks & husk, ground nut shell & stalks, maize stalks & cobs, sunflower stalks, gram stalks, castor stalks & shell and cumin seed stalks etc. (owner to indicate available agro

residues as applicable).


3

Agro residue pellets can be manufactured using single or multiple agro/crop residues together. Any byproduct of wood work factory (such as wood, wood chips, saw dust, furniture waste etc.) shall not be used in manufacture of the biomass pellets. Natural additives/ binder such as lignin, starch, animal dung etc. can be used for manufacturing pellets, if required, by the process. The details of biomass components and natural additives/ binder (if any) likely to be used in manufacture of pellets alongwith their proportions shall be indicated by the bidder in his offer. Further, each consignment to be supplied shall indicate the actual material components & their proportions used in manufacture of biomass pellets. Owner/ Procurer reserves the right to exclude any base material/ additive/ binder or modify their proportion, if any adverse impact of the base material/ additives/ binder is found on boiler in long run.

5.2 Pelletisation and Torrefaction Processes 5.2.1 Pelletisation

A typical description of pelletisation process for agro/ crop residue based biomass is indicated as below:

Biomass (agro/ crop residue) collected from fields / farmers shall be cleaned of soil etc. and shredded to get adequate size material. In case of high moisture content, the shredded material shall be dried to the extent of acceptable moisture level. The dried biomass shall be passed through a screening process to remove bigger size biomass material to be conveyed back to pre-shredding process. The screening system may have magnets also to remove metal particles. The screened dried biomass shall be collected in the hopper placed above hammer mill through bucket elevator. Hammer mill/ grinder shall reduce the biomass to adequate particle size say to less than 2 mm. The biomass from the hammer mill/ grinder shall be pneumatically transferred to a cyclone filter to remove dust particles. The dust free biomass shall be conveyed to the screw feeder to transfer the feed into pellet mill consisting of perforated die of specified diameter holes. The pellets shall be cut to the required size by the cutter attached to the pellet mill. The densified hot biomass pellets, having temperature in the range 80- 1000C, shall be transferred to cooler via drag chain conveyor and shall be cooled by blower or sucking the cold air from the atmosphere. The cooled pellets shall then be transferred to vibrating Screen for removing the fines/ crumbled pellets to be sent back to the hopper above the pellet mill. The proper sized screened pellets shall be collected into storage hopper/ silo through bucket elevator for subsequent transportation to the power plant(s).

5.2.2 Torrefaction A typical description of torrefaction process for agro/ crop residue based biomass is indicated as below:


4

Torrefaction refers to roasting, slow- and mild-pyrolysis, cooking and high-temperature drying of the biomass in a temperature regime between 200 and 3000C under an inert atmosphere. It induces depolymerization and devolatilization of hemicellulose. Major products of biomass torrefaction are solid torrefied biomass and volatiles with composition and yield of products depending on torrefaction temperature, holding time, and biomass physical & chemical properties. Torrefied biomass is brittle and hydrophobic with improved physical and chemical properties such as grindability, storage stability, energy density and has the potential to significantly reduce the cost of transportation, storage, and downstream processing. Torrefaction process shall involve pre- drying the shredded biomass by heating upto about 1000C to evaporate physically bound water. Post- drying and intermediate heating shall be carried out between 100 and 2000C, removing chemically bound water as well as light organic fractions. Further heating will be carried out in the temperature range about 200 to 3000C with adequate holding time for decomposition & release of various volatile species with high oxygen contents. The remaining solid product called torrefied biomass shall mainly comprise of cellulose and lignin and characterized by increased brittleness, hydrophobicity, microbial degradation resistance, and energy density.
